Polishing Machine Polishing Rate
The key to the operation of the polishing machine is to try to get the maximum polishing rate in order to remove the damage layer produced when polished as soon as possible. Polishing Machine But also to make the polishing layer does not affect the final observation of the organization, that is, will not cause false tissue. The former requires the use of coarse abrasive to ensure a greater polishing rate to remove the polished damage layer, but the polishing layer is also deep; the latter requires the use of the finest material, Polishing Machine so that the polishing layer is lighter, but polished Low rate.
The best way to solve this contradiction is to divide the polishing into two stages. Rough cast is to remove the polished damage layer, Polishing Machine this stage should have the largest polishing rate, the rough formation of the surface damage is a secondary consideration, but also should be as small as possible; Polishing Machine followed by fine throw (or final throw) The purpose is to remove rough surface damage caused by roughing, so that polishing damage to a minimum. Polishing machine polishing, the sample grinding and polishing disc should be absolutely parallel and evenly pressed gently on the polishing disc, pay attention to prevent the sample fly out and because the pressure is too large and produce new wear marks. At the same time, Polishing Machine the specimen should be rotated and moved back and forth along the radius of the turntable to avoid local wear of the polished fabric. To keep the powder suspension in the polishing process, Polishing Machine the polished fabric is kept at a certain humidity. The humidity is too large will weaken the grinding of the grinding effect, so that the hard phase of the sample showing the relief and non-metallic inclusions in the steel and cast iron in the graphite phase to produce "trailing tail" phenomenon; Polishing Machine humidity is too small, due to friction heat will make the sample Temperature, lubrication to reduce the grinding surface loss of luster, or even dark spots, light alloy will be wound surface. In order to achieve the purpose of rough throw, requiring the turntable speed is low, it is best not to exceed 600r / min; polishing time should be longer than the time required to remove the scratch, because also remove the deformation layer. Rough cast after grinding smooth, Polishing Machine but dull, in the microscope to observe a uniform and delicate wear marks, to be fine to eliminate.
The speed of the turntable can be properly raised, polished time to throw away the rough throwing layer is appropriate. Fine grinding after grinding as bright as the mirror, Polishing Machine in the microscope under the conditions of the field can not see the scratches, Polishing Machine but in the phase contrast lighting conditions can still be seen grinding marks. Polishing machine polishing quality seriously affect the sample structure, has gradually attracted the attention of experts. At home and abroad in the performance of the polishing machine made a lot of research work, developed a lot of new models, a new generation of polishing equipment, Polishing Machine is the original manual operation developed into a variety of semi-automatic and automatic polishing machine.
Casting light specifically for steel, aluminum and other metal products and the surface of the tube for the effect of treatment, dozens of original parts to meet the different needs, easy to create a variety of different precision of the snow pattern, drawing, wavy, matte Face, mirror, etc., Polishing Machine fast repair depth scratches and slight scratches, quick grinding and polishing; welds, mouth marks, trace oxide film, stains and paint, etc., apply to deburring, forming fillet, decorative metal processing, Polishing Machine In the processing process will not form a shadow, the transition zone and uneven decoration, etc., is an important equipment for the production of metal products
Polishing machine for the following industries: wood, furniture industry, such as flat wood, furniture, metal handle, and other pieces of sanding wire drawing; metal (metal) materials and products aluminum and its products, stainless steel products and utensils, Polishing Machine copper profiles and products, plumbing bathroom equipment Lock, leather goods, signs, brand nameplate, hardware and crafts, knife and scissors, the door of the live leaves, car bicycle parts, tableware category, Ji buckle products, Polishing Machine buttons, belt buckle, Polishing Machine mobile phone shell, watch industry, Light drawing; electronic parts, electronic equipment such as electronic parts, flat sanding, such as drawing.
